FAQ
Customer portal ROI
Understanding ROI
How is the ROI of a customer portal calculated?
The calculator compares the portal investment with the saved service minutes: routine requests such as order status, invoice copies or document downloads are answered by customers themselves in the portal. Depending on the self-service rate (30–60%), a large share of calls and e-mails disappears – resulting in the break-even in months.
Which requests are suited for self-service?
Recurring standard requests have the biggest impact: delivery status, invoice and document copies, master data changes, ticket status and order history. Rule of thumb from our projects: whatever your back office reads out of a system via copy-paste today, a portal can display directly.
After how long does a customer portal pay for itself?
At medium request volumes, break-even typically lands between 6 and 15 months – from saved handling time alone. Faster answers around the clock and relieved service teams come on top as unquantified benefits.

Investment & benefits
What investment does the calculator assume?
Typical project values from our customer portal work: login area, documents, order status and ERP integration – from around EUR 15,000 for focused portals up to EUR 40,000 and more with many processes and systems, excl. VAT.
Which benefits are not included?
Conservatively excluded: higher customer satisfaction through 24/7 availability, fewer errors through self-entry instead of phone transmission, additional revenue via reorder functions and relief for sales, who answer fewer status questions.
What decides whether the portal succeeds or fails?
Adoption. A portal only saves money if customers use it: simple login, real value from the first visit and active communication at launch. Portals that are merely a document archive stay empty – requests then continue via phone and e-mail.
Typical pricing models (overview)
| Model | When it fits | Budget & flexibility | Typical risks |
|---|---|---|---|
| Fixed price (fixed scope) | Clearly defined scope, stable requirements, repeatable delivery. | Predictable total cost; little room for change without a change order. | Scope creep leads to change orders or quality trade-offs. |
| Time & Material | Discovery, legacy, evolving requirements, or close collaboration. | Maximum flexibility; budget transparent via hourly or daily rates. | Without prioritisation, effort can grow—backlog and reviews matter. |
| Retainer / maintenance package | Ongoing operations, updates, small features, and support. | Agreed capacity per month; predictable follow-on cost. | Large changes may still need a separate estimate. |
| Hybrid (milestone + T&M) | MVP or phased releases with clear go-lives, then iterate. | Core delivery fixed price; extensions on a time-and-materials basis. | Define contractually what is in scope vs. extra work. |
